Warning device for road maintenance section in rainstorm weather

Abstract

The invention discloses a warning device for a road maintenance section in rainstorm weather. The warning device comprises a box body, a funnel is arranged on the upper side of the box body, an impeller is arranged on the lower side of the funnel, a first crank is fixedly connected to the front side of the impeller, a first connecting rod is rotationally connected to the front side of the first crank, and a rotating block is arranged on the lower side of the first connecting rod. According to the warning device for the road maintenance section in the rainstorm weather, a cylindrical rail block can be driven to intermittently rotate left and right while a fixed rod rotates, so that a first moving rod is driven to synchronously rotate, and meanwhile, a third connecting rod is intermittently driven to rotate; a convex block is provided on the first moving rod, a clamping groove corresponding to the convex block is formed in the cylindrical rail block, so that the first moving rod is intermittently driven to move up and down, a warning board can rotate left and right and move up and down at the same time, and the structure achieves the effects that the moving warning board is not prone to being ignored, and traffic accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a warning device for road maintenance sections in rainy weather. Background technique [0002] Road maintenance refers to the staged improvement and addition of routes, structures and facilities along the original technical standards that are too low, gradually improving the performance and service level of the road, and continuously meeting the requirements of the whole society for roads. When a certain road section is maintained , It is necessary to place warning signs at the beginning and end of the road section, but in the face of heavy rain, the driving line of sight is not good, and it is easy to ignore the warning signs. [0003] At present, most of the warning signs on the market mainly exist in the state that the warning signs are always in a static state, making it easy to ignore the static warning signs due to the poor sight of driving in rainy weather, making...

Problems solved by technology

[0002] Road maintenance refers to the staged improvement and addition of routes, structures and facilities along the original technical standards that are too low, gradually improving the performance and service level of the road, and continuously meeting the requirements of the whole society for roads. When a certain road section is maintained , it is necessary to place warning signs at the beginning and end of the road section, but in the face of heavy rain, the driving line of sight is not good, and it is easy to ignore the warning signs

[0003] At present, most of the warning signs on the market mainly exist in the state that the warning signs are always in a static state, making it easy to ignore the static warning signs due to the poor sight of driving in rainy weather, making it easy to cause traffic accidents. Or there may be a device that can rotate the warning light board intermittently, but the unilateral warning by turning the warning light board intermittently makes the warning device unique, resulting in poor warning effect

The above situation will lead to the problems that it is easy to ignore the static warning signs, easily cause traffic accidents, the warning device is single and the warning effect is not good.
